Description

  The present invention relates to a hydrocarbon system for reforming heavy oils such as distillation residues generated in petroleum refining, natural heavy oils such as oil shale, plastics waste, hydrocarbon heavy materials such as coal, coal tar, etc. The present invention relates to a method for reforming heavy materials.

  As a method for reforming this kind of hydrocarbon heavy raw material, hydrocarbon resources (hydrocarbon heavy raw material) are primarily decomposed (superheated) in supercritical water to become a base material such as light oil. In addition to obtaining the product, the residual component (residual heavy component) remaining in the primary decomposition is subjected to secondary decomposition (secondary thermal decomposition) in higher-temperature supercritical water to generate a gas mainly composed of hydrogen. And a method of burning the residual components remaining in the secondary decomposition is known (for example, Patent Document 1).

  In the reforming method of the hydrocarbon heavy material, a reformed product having a relatively low boiling point can be recovered by primary decomposition. In this case, the recovery rate of the reformed product can be increased by increasing the primary decomposition temperature.

  However, when the primary decomposition temperature is raised, the decomposition of hydrocarbon resources proceeds excessively, so impurities such as sulfur, nitrogen, and various metals contained in the hydrocarbon resources are mixed into the reformed product. The ratio to do increases. In addition, since the residual component in the primary decomposition has a high viscosity, it easily accumulates in the primary decomposition region, and also causes the inside of the apparatus constituting the primary decomposition region to be blocked.

In addition, when the primary decomposition temperature is lowered, there is an advantage that the ratio of impurities mixed into the reformed product is reduced, the viscosity of the residual component is lowered, and the handling of the residual component is simplified. However, there is a problem that the recovery rate of the modified product that becomes the base of the product oil is reduced.
Japanese Patent No. 3499478

  The present invention has been made in view of the above circumstances, and it is possible to recover a large amount of a reformed product that becomes a base of product oil having high value such as light oil, and to mix impurities into the reformed product. It is an object of the present invention to provide a method for reforming a hydrocarbon-based heavy feedstock that can reduce the amount and that can easily handle residual heavy components.

  In order to solve the above-mentioned problem, the invention described in claim 1 is a method for reforming a hydrocarbon-based heavy raw material in which a hydrocarbon-based heavy raw material is subjected to a reforming process accompanied by lightening, The hydrogen-based heavy raw material is charged into the first pyrolysis region containing 300 to 500 ° C. containing water vapor and subjected to the reforming treatment, and then heat is generated from the hydrocarbon-based heavy raw material in the first pyrolysis region. The light component separated by the decomposition is transferred to the second thermal decomposition region of 400 to 600 ° C. together with the water vapor and further reformed to obtain a reformed product.

  The invention according to claim 2 is the invention according to claim 1, wherein residual heavy components other than the light components separated from the hydrocarbon heavy material by pyrolysis in the first pyrolysis region are added. It discharges | emits from the said 1st pyrolysis area | region at the temperature below the said 1st pyrolysis area | region.

  According to a third aspect of the present invention, in the second aspect of the invention, the residual heavy component discharged from the first thermal decomposition region is transferred to an oxidation reaction region, and the residual weight is transferred in the oxidation reaction region. The heat of oxidation reaction generated by oxidizing the quality component is used for heating the first pyrolysis region and / or the second pyrolysis region.

  The invention according to claim 4 is the invention according to claim 3, wherein the high-temperature fluid generated by the oxidation reaction of the residual heavy component in the oxidation reaction region is converted into the first pyrolysis region and / or the first. It supplies to the 2 pyrolysis area | region, It uses for the heating of the said 1st pyrolysis area | region and / or 2nd pyrolysis area | region.

  Invention of Claim 5 arrange | positions the said 1st thermal decomposition area | region, the said 2nd thermal decomposition area | region, and the said oxidation reaction area | region in the same reaction container in the invention of Claim 3 or 4, The high-temperature fluid generated in the oxidation reaction region is directly supplied into the first pyrolysis region and / or into the second pyrolysis region.

  A sixth aspect of the invention is characterized in that, in the invention of the fourth or fifth aspect, the high temperature fluid is generated by a partial oxidation reaction of the residual heavy component.

  According to the invention described in claims 1 to 6 configured as described above, by introducing the hydrocarbon-based heavy raw material into the first thermal decomposition region at 300 to 500 ° C., the lightness having a relatively low boiling point. Ingredients can be removed. In this case, since the temperature of the first pyrolysis region is set to 300 ° C. or higher, a sufficient amount of light components can be taken out. In addition, since the temperature of the first pyrolysis region is set to 500 ° C. or less, impurities such as sulfur, nitrogen, various metals and the like that are likely to generate coke are contained in the hydrocarbon heavy material. Can be reduced in the light components.

  Then, the light component separated in the first pyrolysis region is transferred to the second pyrolysis region together with water vapor and further pyrolyzed in the second pyrolysis region, thereby further reducing the light component. A product can be obtained. In this case, since the temperature of the second pyrolysis region is set to 400 ° C. or higher, a modified product can be obtained by further lightening or desulfurization of the light component. Therefore, it is possible to recover a large amount of the reformed product that becomes a base of product oil having high value such as light oil.

  Moreover, since the temperature of the second thermal decomposition region is set to 600 ° C. or less, the occurrence of coking in the light component can be sufficiently suppressed. Note that the occurrence of coking can also be suppressed because the proportion of the components that easily generate coke mixed with the light components in the first thermal decomposition region described above is reduced. Therefore, a modified product with very little impurities and coke can be obtained.

  According to the second aspect of the present invention, residual heavy components other than the light components separated in the first pyrolysis region are discharged from the first pyrolysis region at a temperature equal to or lower than the first pyrolysis region. Therefore, it is possible to prevent the residual heavy component from being excessively heated in combination with the first thermal decomposition region being suppressed to 500 ° C. or lower. For this reason, since it is possible to prevent the viscosity of the residual heavy component from being increased, the residual heavy component is deposited in the first pyrolysis region or the first pyrolysis region is blocked. Can be prevented. Therefore, handling of residual heavy components is simplified.

  In addition, as temperature below the said 1st thermal decomposition area | region, it is preferable to set it as 100-500 degreeC. The reason is that if it is less than 100 ° C, the viscosity of the residual heavy component becomes high and it becomes difficult to discharge from the first pyrolysis region. If it exceeds 500 ° C, excessive heating of the residual heavy component or the residual This is because the viscosity increases due to the caulking of the heavy component, and in this case, it is difficult to discharge from the first pyrolysis region.

  According to the third aspect of the present invention, the residual heavy component discharged from the first thermal decomposition region is oxidized in the oxidation reaction region, and the oxidation reaction heat is converted into the first thermal decomposition region and / or the second heat. Since it is used for heating the cracking zone, the residual heavy components can be used effectively as a heat source for reforming hydrocarbon heavy materials, and the residue that will eventually become waste is reduced. be able to.

  According to the invention described in claim 4, the high-temperature fluid generated by the oxidation reaction of the residual heavy component is directly supplied from the oxidation reaction region to the first thermal decomposition region and / or the second thermal decomposition region, Since it is used for heating the first thermal decomposition region and / or the second thermal decomposition region, the heat generated by the oxidation reaction can be efficiently supplied to each of the thermal decomposition regions.

  According to the fifth aspect of the present invention, the first pyrolysis region, the second pyrolysis region, and the oxidation reaction region are arranged in the same reaction vessel, and the high-temperature fluid generated in the oxidation reaction region is Since the gas is directly supplied into the pyrolysis region and / or the second pyrolysis region, it is possible to reduce the size of the apparatus configured to reform the hydrocarbon-based heavy raw material, and it is generated by oxidation. The useful gas in the hot fluid can be recovered as a reformed product via the first pyrolysis region and / or the second pyrolysis region.

According to the invention described in claim 6, the high-temperature fluid is subjected to partial oxidation reaction of residual heavy components (that is, incomplete combustion performed under an oxygen amount smaller than the theoretical oxygen amount that completely burns the residual heavy components). Therefore, it is possible to generate useful gases such as H ₂ , CH ₄ , and CO. The generated H ₂ can be hydrogenated to unsaturated bonds of light components generated by thermal decomposition, and the light components can be modified to become a modified product that becomes a valuable base material such as light oil. At the same time, it can be recovered as a reformed product that becomes a base material of useful fuel that can be used in fuel cells, gas turbines, and the like together with CH ₄ and CO.

Further, with respect to the CO, for example, the following equation (1) is obtained by pressurizing the first pyrolysis region and the second pyrolysis region described above to a subcritical (high pressure steam) or supercritical atmosphere state of steam. Since the reaction shown in (2) occurs actively and can contribute to the generation of hydrogen, it is useful for reforming light components in the first pyrolysis region or the second pyrolysis region.
CO + H ₂ O → CO ₂ + H ₂ (1)

(First embodiment)
A first embodiment as the best mode for carrying out the present invention will be described with reference to the drawings.

  The hydrocarbon heavy material reforming apparatus shown in the first embodiment, as shown in FIG. 1, performs a reforming process that involves lightening heavy oil (hydrocarbon heavy material). 1st pyrolysis area | region structure part (1st pyrolysis area | region) 1, 2nd pyrolysis area | region structure part (2nd pyrolysis area | region) 2, and residual heavy component accommodating part 3 It is the composition provided with. Moreover, heavy oil has shown what corresponds to asphalt after carrying out vacuum distillation in an oil refinery facility.

  The first pyrolysis region constituting unit 1 is configured such that heavy oil is supplied together with water therein, and the inside thereof is maintained in a state heated to a temperature of 300 to 500 ° C. It has become. In addition, the pressure in the first pyrolysis region component 1 is pressurized to a pressure around the critical point of water (about 22.1 MPa) to a high temperature and high pressure state such as high-pressure steam or supercritical water. It has become. The temperature at the critical point of water is about 374 ° C.

  In the second pyrolysis region component 2, the component A as a light component separated from the heavy oil by pyrolysis in the first pyrolysis region component 1 is entrained in high-temperature and high-pressure steam. In addition to being supplied in a state, the inside is maintained at a temperature of 400 to 600 ° C. Further, the pressure in the second pyrolysis region constituting unit 2 is slightly lower than the pressure in the first pyrolysis region constituting unit 1, but is maintained at the same level as the first pyrolysis region constituting unit 1. It has come to be.

  Further, the component B as the residual heavy component other than the component A separated from the heavy oil in the first pyrolysis region constituting unit 1 is a temperature equal to or lower than the temperature of the first pyrolysis region constituting unit 1 100. While being maintained at ˜500 ° C., it is discharged from the first pyrolysis region constituting unit 1.

  The residual heavy component storage unit 3 stores the component B discharged from the first pyrolysis region constituting unit 1.

  In the reforming method using the hydrocarbon heavy material reforming apparatus configured as described above, heavy oil is introduced into the first pyrolysis region constituting unit 1 at 300 to 500 ° C. containing water vapor. After the reforming treatment, the component A separated from the heavy oil by pyrolysis in the first pyrolysis region component 1 is transferred to the second pyrolysis region component 2 at 400 to 600 ° C. together with water vapor. The modified product C is further reformed to obtain a modified product C.

  And in the state which maintained the components B other than the component A isolate | separated in the 1st pyrolysis area | region structure part 1 at 100-500 degreeC which is the temperature below the temperature of the 1st pyrolysis area | region structure part 1. 1 is discharged from the thermal decomposition region constituting unit 1.

  Further, the reformed product C after reforming the component A in the second pyrolysis region constituting unit 2 is sent to the existing refining processing unit 4 such as gasoline, kerosene, light oil, etc. in the above-described petroleum refining equipment, and the modified The quality product C is used as a base material for producing light oil or the like.

  In the hydrocarbon heavy raw material reforming apparatus and reforming method configured as described above, by introducing heavy oil into the first pyrolysis region constituting part 1 at 300 to 500 ° C., the boiling point of A relatively low component A can be separated.

  In this case, since the temperature of the 1st pyrolysis area | region structure part 1 is set to 300 degreeC or more, comparatively much component A can be taken out. Moreover, since the temperature of the 1st pyrolysis area | region structure part 1 is set to 500 degrees C or less, it is easy to generate | occur | produce impurities, such as sulfur, nitrogen, various metals, etc. which are contained in heavy oil, and coke. The proportion of components and the like mixed into component A can be reduced.

  In addition, the component A is further thermally decomposed in the second pyrolysis region constituting unit 2 and subjected to reforming treatment such as lightening. In this case, since the inside of the second pyrolysis region constituting part 2 is in a state of high-pressure steam or supercritical water at 400 ° C. or higher, further lightening of component A, reforming such as desulfurization, etc., is allowed to proceed. Can do.

  Furthermore, since the temperature of the pyrolysis region of the second pyrolysis region component 2 is set to 600 ° C. or less, the occurrence of coking in the component A can be sufficiently suppressed. This coking can also be suppressed because the proportion of components that are likely to generate coke into component A is reduced.

  Accordingly, it is possible to recover a large amount of the modified product C that becomes a base of product oil having a high value such as light oil, and it is possible to obtain an extremely small amount of impurities and coke as the modified product C.

  Furthermore, since the component B is discharged from the first pyrolysis region constituent unit 1 at a temperature equal to or lower than the first pyrolysis region constituent unit 1, the first pyrolysis region constituent unit 1 is 500 ° C. Combined with being suppressed below, component B can be prevented from being excessively heated and thermally decomposed. For this reason, since it can prevent that the viscosity of the component B becomes high, the component B accumulates in the 1st pyrolysis area | region structure part 1, the said 1st pyrolysis area | region structure part 1 grade | etc., Etc. It is possible to prevent obstruction. Therefore, the handling of the component B becomes extremely simple.

  In addition, the temperature of the first pyrolysis region constituting unit 1 or lower is set to 100 to 500 ° C. If the temperature is less than 100 ° C., the viscosity of the component B becomes high and it is difficult to discharge from the first pyrolysis region constituting unit 1. If the temperature exceeds 500 ° C., the viscosity of the component B increases due to excessive heating of the component B or coking of the component B, and in this case also, the discharge from the first pyrolysis region constituting unit 1 becomes difficult. Because.

{Different forms for carrying out the invention}

  Next, a second embodiment and a third embodiment as different modes for carrying out the present invention will be described with reference to the drawings.

(Second Embodiment)

  First, a second embodiment will be described with reference to FIG. However, elements common to the constituent elements shown in the first embodiment are denoted by the same reference numerals, and description thereof is simplified.

  The hydrocarbon heavy material reforming apparatus shown in the second embodiment is different from the hydrocarbon heavy raw material reforming apparatus shown in the first embodiment in the first pyrolysis region. The component B discharged from the component 1 is transferred to the oxidation reaction region component (oxidation reaction region) 5, and the oxidation reaction heat generated by the oxidation reaction of the component B in this oxidation reaction region component 5 is first pyrolyzed. It is the point used for the heating of the area | region structure part 1 and the 2nd pyrolysis area | region structure part 2. FIG.

  That is, the oxidation reaction region constituting unit 5 is supplied with the component B, and is supplied with water and an oxidizing agent (mainly oxygen, which may be air or the like). The supply amount of the oxidizing agent into the oxidation reaction region constituting unit 5 is limited so that the partial oxidation reaction (incomplete combustion) of the component B occurs.

  Further, the oxidation reaction heat described above directly supplies the high-temperature gas (high-temperature fluid) generated by the oxidation reaction of component B into the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2. Is used to heat the first pyrolysis region component 1 and the second pyrolysis region component 2 in order to maintain the temperature in the above-described temperature.

  Further, the high temperature gas generated in the oxidation reaction region constituting unit 5 is used for preheating heavy oil and water supplied to the first pyrolysis region constituting unit 1 and others. Further, the hydrogen in the high temperature gas is supplied to the purification processing unit 4 and used for purification. In FIG. 2, 5a is a heat exchanger for transferring the heat of the high temperature gas to the heavy oil, and 5b is a heat exchanger for transferring the heat of the high temperature gas to the water.

  In addition, the temperature in the oxidation reaction region constituting unit 5 is maintained at 800 to 1200 ° C., and a high-temperature gas having a temperature corresponding to this temperature is generated in the first pyrolysis region constituting unit 1 and the second It is supplied directly to the pyrolysis region component 2 and others. The high-temperature gas having the above temperature is mixed with, for example, lower-temperature water vapor to adjust the temperature, and then supplied to the first pyrolysis region component 1, the second pyrolysis region component 2, and others. May be.

  Further, the high temperature gas generated in the oxidation reaction region constituting unit 5 is supplied to the first pyrolysis region constituting unit 1, the second pyrolysis region constituting unit 2, and the like. For this reason, the oxidation reaction region constituting unit 5 is in an atmospheric state of high-pressure steam or supercritical water having a higher pressure than the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2.

  In the reforming method using the hydrocarbon heavy material reforming apparatus configured as described above, the component B discharged from the first pyrolysis region constituting unit 1 is transferred to the oxidation reaction region constituting unit 5. The oxidation reaction heat generated by the oxidation reaction of component B in the oxidation reaction region constituting unit 5 is used for heating the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2.

  Further, by supplying the high-temperature gas generated by the incomplete combustion of the component B directly into the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2, the first pyrolysis region The component 1 and the second pyrolysis region component 2 are heated and supplied to the heat exchangers 5a and 5b to be used for heating heavy oil or water.

  In the hydrocarbon heavy material reforming apparatus and reforming method configured as described above, the component B discharged from the first pyrolysis region constituting unit 1 is oxidized by the oxidation reaction region constituting unit 5, Since the oxidation reaction heat is used for heating the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2 and the like, the component B is effectively used as a heat source for reforming heavy oil. In addition, it is possible to reduce residues that eventually become waste.

  Further, the high-temperature gas generated by the oxidation reaction of component B is supplied from the oxidation reaction region constituting unit 5 to the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2, and the first pyrolysis is performed. Since it uses for the heating of the area | region structure part 1 and the 2nd thermal decomposition area | region structure part 2, the motive power for conveying high temperature gas becomes unnecessary. Therefore, energy efficiency can be improved.

  Moreover, since the high-temperature gas generated in the oxidation reaction region constituting unit 5 is directly supplied into the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2, useful gas in the high-temperature gas is supplied. The reformed product C can be recovered through the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2.

Furthermore, since the high-temperature gas is generated by the partial oxidation reaction (incomplete combustion reaction) of component B, useful gases such as H ₂ , CH ₄ , and CO can be generated. The H ₂ generated here is modified so that the component A in the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2 becomes a modified product C which becomes a base material for product oil such as light oil. In addition to CH ₄ and CO, it can be recovered as a reformed product C that becomes a base material for fuel such as fuel cells and gas turbines.

  Further, the CO can contribute to the generation of hydrogen by the reaction of the above-described formula (1).

  The reason why the temperature in the oxidation reaction region constituting part 5 is set to 800 to 1200 ° C. is that if it is less than 800 ° C., the oxidation reaction rate is not sufficient, and unreacted residues are likely to remain. This is because if the temperature exceeds ° C., problems such as insufficient strength may occur in the members constituting the oxidation reaction region constituting portion 5 and the like.

(Third embodiment)

  Next, a third embodiment will be described with reference to FIG. However, the same reference numerals are given to the elements common to the constituent elements shown in the second embodiment, and the description will be simplified.

  The hydrocarbon heavy material reforming apparatus shown in the third embodiment is different from the hydrocarbon heavy raw material reforming apparatus shown in the second embodiment in the first pyrolysis region. It is the point which is comprised so that the structure part 1, the 2nd thermal decomposition area | region structure part 2, and the oxidation reaction area | region structure part 5 may be accommodated in the same reaction container 6. FIG.

  In FIG. 3, reference numeral 5 c denotes a pump for supplying the component B to a combustion nozzle provided in the oxidation reaction region constituting unit 5 in order to actively burn the component B as fuel.

  In the reforming method using the hydrocarbon heavy material reforming apparatus configured as described above, the high-temperature gas generated in the oxidation reaction region constituting unit 5 in the reaction vessel 6 is put into the same reaction vessel 6. It supplies directly in the 1st pyrolysis area | region structure part 1 and the 2nd pyrolysis area | region structure part 2 which are arrange | positioned.

  In the hydrocarbon heavy material reforming apparatus and reforming method configured as described above, the first pyrolysis region constituting unit 1, the second pyrolysis region constituting unit 2, and the oxidation reaction region constituting unit 5 are used. Are arranged so as to be accommodated in the same reaction vessel 6, the hydrocarbon heavy material reforming apparatus can be made compact.

  In each of the above embodiments, the example in which the temperature in the first pyrolysis region constituting unit 1 is maintained at 300 to 500 ° C. has been shown, but it is more preferable to maintain this temperature at 380 to 450 ° C. . The reason is that by setting the above temperature to 380 ° C. or higher, the yield of component A can be further increased, the viscosity of component B is reduced, and the fluidity of component B is maintained in a more appropriate range. Because you can. Moreover, it is because the ratio in which the impurity in the component B, the component which is easy to generate | occur | produce coke, etc. transfers to the component A can be reduced more by making the said temperature into 450 degrees C or less.

  Moreover, although the example which maintains the temperature in the 2nd pyrolysis area | region structure part 2 at 400-600 degreeC was shown, it is more preferable to maintain this temperature at 430-520 degreeC. That is, when the temperature is lower than 430 ° C., there is a relatively heavy component in the modified product C after reforming the component A, so that the modified product C is used as a base material for purification. Even if it refines with the processing part 4, the ratio of the product oil with a low value like C heavy oil will increase.

  On the other hand, when the temperature exceeds 520 ° C., the proportion of light gaseous components contained in the reformed product C increases, while the proportion of components that become product oil is contained in the reformed product C. Will be reduced. Moreover, since the proportion of aromatics in the component that becomes the product oil increases, even if the refined product containing the component is refined by the refining processing unit 4, the proportion of product oil that is less valuable than heavy oil A is still present. Become more. Further, since the light component in the component A is further excessively decomposed, the process load (residual carbon amount and The load due to the diene compound) will increase.

  Therefore, the temperature in the second pyrolysis region constituting unit 2 is more preferably set to 430 to 520 ° C. as described above.

  In the second and third embodiments, the high temperature gas is supplied to both the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2. The gas is supplied to one of the first pyrolysis region constituting unit 1 and the second pyrolysis region constituting unit 2, and the other not supplied with the high temperature gas is heated by another heating means or the like. May be.

  Moreover, you may comprise so that the heat | fever of high temperature gas may be indirectly supplied to the 1st pyrolysis area | region structure part 1 or the 2nd pyrolysis area | region structure part 2 via a heat exchanger etc.
